Filed: 1993-01-21
Abstract: PURPOSE:To maintain the specified flying height of a magnetic head regardless of the position on a magnetic disk of the magnetic disk device having actuators of linear and rotary types. CONSTITUTION:The front and rear 2 surfaces of the magnetic disk 1 are respectively provided with the actuators 5. Linear guides 10 of the actuators of the linear type are inclined with the magnetic disk 1 in such a manner that the pressing force on the magnetic head 3 decreases according to the movement of the magnetic head 3 from the outer periphery toward the inner periphery. The revolving shafts of the actuators of the rotary type are inclined in two ways with respect to the magnetic disk surface so as to maximize the pressing force in the middle peripheral part and to minimize the pressing force in the inner peripheral part respectively. Consequently, the specified flying height of the head is maintained regardless of its positions and the storage capacity is increased. The min. flying height is highly held, the danger of a head crash is decreased and the reliability of the device is improved. The number of the heads per piece of the actuators is halved and the access speed is increased.

Title: Color image data coding method
Inventor: WATAYA MASAFUMI
IPC: H04N11/04
Filed: 1994-01-28
Abstract: PURPOSE:To effectively code the color image data. CONSTITUTION:The RGB signals of a small block are acquired via a line buffer 301 which temporarily stores the input RGB signals for segmentation of blocks. Then the RGB signals of the small block undergo the L*a*b* conversion 302, for example, of a color coordinate system having less signal correlation. The lightness information L* is successively sent to the block L0, L1...LF and undergoes the orthogonal conversion 304. A coefficient F0 305 represents the block lightness, and the coefficients F1-FF 306 represent the edge structures included in the blocks. The coefficient F0 305 transmits the information L* through a quantizer 307, and the coefficients 306 transmit the structure information S through a quantizer 309. Meanwhile, a* and b* are averaged (311 and 312) respectively and put together as the color information C by a quantizer 313. These information L, S and C are joined together by a multiplexer 315 and transmitted. In other words, the color image data are divided into plural pieces of information, undergo each suitable pre-processing, and are effectively coded.

Abstract: PURPOSE:To increase a value of a reading current by providing a second bit line connected to a plurality of bit line group and a plurality of first virtual ground line, and a switch element provided between the second virtual ground line and the second and first bit lines. CONSTITUTION:A reading current (i) flows to a ground through a circuit of a main bit line MB1, a M0SFETSO2, a subbit line SB2, a memory cell Mm2K, a subground SG2 and a main ground line MG2. When diffused resistances of the lines SB2 and SG2 are R1 and R2, a total resistance value becomes R1+R2 (=nr), This resistance value is constant irrespective of a position of a memory cell. Accordingly, even if the position of the cell is varied, a value of the current (i) is constant. Further, since a value of the diffused resistance becomes 1/2 of the maximum value (2mr) of the case of a conventional example, the value of the current (i) is increased.

Filed: 1984-01-20
Abstract: PURPOSE:To decrease the opposing width of the comb-shaped electrodes and to increase the impedance by providing a diffusing means of surface waves at an outer edge part rolling approximately along the propagating direction of the surface wave of an electrode formed on a piezoelectric substrate. CONSTITUTION:The grooves 6 are cut above an input electrode 2, an output electrode 3 and an earth electrode 4 with a sawtooth-shaped pattern so that these grooves cross outer edges 2a, 2b, 3a, 3b, 4a and 4b of electrodes 2-4 respectively. Thus a means 5 which diffuses undesired surface waves, and therefore the effects of undesired waves can be avoided. This reduces satisfactorily the opposing width (w) of comb-shaped electrodes and increases the impedance. Thus it is not needed that the distance (d) between the opposing part and the outer edge of an electrode is set there times as much as the wavelength. As a result, the overall size of a surface element can be reduced.

Filed: 1987-01-19
Abstract: PURPOSE:To easily carry out the proper recording by taking up a recording paper from a nearly cylindrical driving-out means and press-urging the shaft edge surface of the driving-out means and pulling-urging the recording paper in the reverse direction to the taking-up direction, thus preventing the excessive discharge due to inertia.

When the taking-up part is driven, the recording paper is pulled out, applied with brake, in the state where the brake power is balanced with the coil spring 127 and the thin leaf spring 160. Therefore, the excessive discharge by inertia is prevented, and the proper recording can be carried out without generating slack.

Title: Check valve
Inventor: YAMAUCHI MASAHARU
IPC: F04B53/10
Filed: 1989-01-18
Abstract: PURPOSE:To suppress the fluctuation of the fuel passing a check valve small and prevent the occurrence of noise by providing a semicircular valve section seated on a valve seat section provided at one end of a shaft section and a collar-shaped stable section surrounding the periphery of the valve section on the shaft section side of the valve section. CONSTITUTION:When a stable section 33 is provided on the valve body 30 of a check valve 8, the force applied by the discharged fuel is increased, the force to lift the valve body 30 against the force of a spring 30 is increased, thus the valve body 30 is suppressed, and self-excited vibration (oscillating phenomenon) is suppressed. When the valve body 30 itself has the stable section 33, the inertial moment against the self-excited vibration is increased, and the frequency of the self-excited vibration is decreased. This action occurs regardless of the contact between the stepped section 311 of the shaft section 31 of the valve body 30 and the valve body receiving section 23 of a stopper 20. The fluctuation of the fuel passing the check valve 8 can be suppressed small, and noise is rarely generated by the induction of car body vibration.

Filed: 1985-01-22
Abstract: PURPOSE:To form a very narrow impurity diffused region, by utilizing plane orientation dependency of an etching speed as found in an Si etching liquid. CONSTITUTION:On the surface of an (100) Si substrate, an oxide film 2 is formed. A window having a width l1 is formed by photolithography. A groove having a depth l2 is formed by an etching liquid such as aqueous solution of KHO, which performs selective etching of a (100) plane. At this time the etching is stopped at the side surface of (111) or equivalent plane (111). The side surface of the substrate 1 forms the slant surface of 54.7 deg.. Impurities are introduced in the part of the groove by gaseous phase thermal diffusion, ion implantation and the like, and a diffused layer 4 having a thickness of l3 is formed. Then the same etching is performed, and the groove is deepened by the depth of l4. The diffused layer 4, which is formed on the side surface, remains intact since the etching in the direction of (111) hardly advances. A slender diffused layer 5 having a width l5 is formed in the shape of the contour of the groove.

Consequently, the substances 10 adhering to the wall of the reaction vessel 1 and the blades of a stirring apparatus are washed out by simultaneous application of the mechanical force and dissolution force and together with the washing liquid 9, the substances 10 fall to the lower part of the reaction vessel 1. The washing liquid 9 is again taken out through the bottom valve 4, sent to the nozzle 7 while being pressurized, and used repeatedly for washing.
